Abstract
Description
Die Erfindung bezieht sich auf eine Zwischenscheibe für benachbarte Glieder, die vorzugsweise relativbeweglich zueinander ausgebildet sind nach dem Oberbegriff des Patentanspruchs 1.The invention relates to an intermediate disc for adjacent members, which are preferably designed to be relatively movable relative to one another according to the preamble of patent claim 1.
An eine Gelenkvorrichtung, bestehend aus zwei relativbeweglichen Elementen, die als Lenker eines Gestänges für ein bewegliches Dach eines Kraftfahrzeugs eingesetzt -nicht veröffentlichte
Es ist eine Unterlegscheibe für eine Schraubenbefestigung an einem emaillierten Blech bekannt,
In der
Aus der
Es ist Aufgabe der Erfindung, eine Zwischenscheibe für benachbarte Glieder, die relativbeweglich zueinander ausgebildet sind, zu schaffen, die sich durch besondere Haltbarkeit, Korrosionsarmut und niedrige Reibung auszeichnet. Dabei sollte die Zwilschenscheibe aber auch in der Weise wirken, dass das Lagerspiel in axialer Richtung gering ist.It is an object of the invention to provide an intermediate disc for adjacent members, which are relatively movable to each other, which is characterized by particular durability, low corrosion and low friction. However, the Zwi disc should also act in such a way that the bearing clearance in the axial direction is low.
Nach der Erfindung wird diese Aufgabe durch die Merkmale des Patentanspruchs 1 gelöst. Weitere, die Erfindung ausgestaltende Merkmale sind in den Unteransprüchen enthalten.According to the invention, this object is solved by the features of patent claim 1. Further, the invention ausgestaltende features are included in the subclaims.
Die mit der Erfindung hauptsächlich erzielten Vorteile sind darin zu sehen, dass die Zwischenscheibe für die relativbeweglichen Glieder in der beanspruchten technischen Ausprägung eine hohe Standzeit sicherstellt, und weil aus definiertem Kunststoff bestehend, ist sie auch wenig korrosionsanfällig. Hervorzuheben ist auch, dass die Zwischenscheibe ein günstiges Reibverhalten besitzt und zur Axialspielreduktion beiträgt. Die Zwischenscheibe eignet sich u.a. für Gelenkvorrichtungen mit drehbaren Lenkern, wie sie bei beweglichen Dächern von Kraftfahrzeugen eingesetzt werden, und sie gleicht axiale Toleranzen bei derartigen Gelenkvorrichtungen vorbildlich aus. Hierzu tragen die Vorsehung und die Anordnung der als Auflageebenen dargestellten Stützorgane und die Federabschnitte bei. Letztere sind mit der gewählten Konfiguration leicht an der Zwischenscheibe realisierbar.The advantages achieved by the invention are to be seen in the fact that the washer for the relatively movable members in the claimed technical specification ensures a long service life, and because consisting of defined plastic, it is also less susceptible to corrosion. It should also be emphasized that the washer has a favorable friction behavior and contributes to the reduction of axial play. The washer is u.a. for articulated devices with rotatable handlebars, as used in moving roofs of motor vehicles, and it compensates for axial tolerances in such articulated devices exemplary. For this purpose, the providence and the arrangement of the support members shown as bearing levels and the spring sections contribute. The latter are easily realized with the selected configuration on the washer.

Zwischen erstem Bolzenkopf 12 und zweitem Bolzenkopf 13 erstreckt sich ein Bolzenschaft 14, der Bohrungen 15 und 16 der Glieder 1 und 2 durchdringt. Der Bolzenschaft 14 ist mit Stufenabschnitten 17 und 18 versehen, wobei der Durchmesser DI des Stufenabschnitts 17 größer ist als der Durchmesser DII des Stufenabschnitts 18. Der Stufenabschnitt 17 kann mit einem Anschlag 19 versehen sein, an dem das Glied 2 anliegt.The
Die mit Anschlagseiten 20 und 21 für Lagerabschnitte 22 und 23 der Glieder 1 und 2 versehene Zwischenscheibe 7 dient zum Ausgleich von Toleranzen namentlich Axialspiel zwischen den Gliedern 1 und 2 und besteht aus Kunststoff, der hohe Druckfestigkeit bei hoher Dehnung aufweist. Hierfür eignet sich bspw. Polyetraflourethylen PTFE oder ein anderer geeigneter Kunststoff. Die Zwischenscheibe 7 ist auf beiden Anschlagseiten 20 und 21 mit Stützorganen Stol und Stoll versehen, die mit radialem Versatz Vra an der Ringscheibe 9 vorgesehen sind. Zwischen benachbarten Stützorganen Stol oder Stoll verlaufen Federabschnitte Fsl und FSII. Jeder Federabschnitt Fsl oder FsII ist gegenüber der höchsten Stelle Sh der Stützorgane Stol oder Stoll in axialer Richtung Ra der Zwischenscheibe 7 abgesetzt, was mit dem Abstand As verdeutlicht ist.The provided with
Die höchsten Stellen Sh der Stützorgane Stol und Stoll sind als Auflageebenen 24 für die Lagerabschnitte 22 und 23 der Glieder 1 und 2 versehen. Die Maßabstimmung der Auflageebenen 24 in axialer Richtung der Zwischenscheibe 7, und zwar auf beiden Anschlagseiten 20 und 21 in Verbindung mit den Federabschnitten Fsl und Fsll erfolgt empirisch.The highest points Sh of the support members Stol and Stoll are provided as bearing
Eine gute Funktion wird erreicht, wenn auf jeder Anschlagsseite 20 und 21 jeweils fünf gleichmäßig verteilte Auflageebenen 24 eingearbeitet sind. Die Auflageebenen 24 verjüngen sich konisch, und zwar in radialer Richtung des Zentrums Z der Ringscheibe 9 der Zwischenscheibe 7. Dabei ist jede Auflageebene 24 auf einer dem Zentrum Z zugekehrten Seite 25 durch einen Radius R begrenzt. Aus Fig. 2 ist ersichtlich, dass die Auflageebenen 24 radiale Begrenzungen 26 und 27 aufweisen, die einen Winkel α von 22° bis 24° einschließen. Schließlich sind bei der dargestellten Zwischenscheibe 7 die Flächen der Auflageebenen 24 kleiner als die Flächen der Federabschnitte Fsl oder FsII.A good function is achieved if on each
